IMPROVEMENT IN FOUNTAIN-FEMS.

I Specification forming part of Letters Patent No. l93,0-7 I, dated July17, 1877; application filed I June 19, 1877.

To all whom it may concern:

Be it known that. I, HENRY O. BENSON, of Yonkers, in the county ofWestchester and State of New York, have invented certain new and usefulImprovements in Pens; and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable othersskilled in the art to which it appertains to make and use the same,reference being bad to the accompanying drawings, andto the letters ofreference marked thereon, which form a part of this specification.

This invention relates to that kind-of pen which is provided with asoluble solid ink or writing material, so arranged that when the pen isdipped in water said material will, to a certain extent, dissolve in thewater held by the pen, and thus produce an ink or writingfluid, whichwill be given off by the pen in the usual way.

I am aware that a pen in which the combination above named is found hasbefore been made.

My invention relates to the means for bolding and maintaining the solidwriting material in proper position with relation to the pen.

It is my object to combine the pen and the means aforesaid in such amanner as to admit of the solid ink being renewed as often as required.

It is further my object to produce such a combination of the partsspecified as will permit the pen to be removed and replaced withoutinterference with the writing material or the means for holding thesame.

In the drawings accompanying this specification there are shown articlesin which both A of the results above mentioned are arrived at.

The pens shown in the drawings are represented on an enlarged scale.

Figures 1, 2, and 3 are each a longitudinal central section of a penembodying my invention.

In Figs. 1 and 2 the clasp that retains the ink-solid is part and parcelof the interior barrel or tube of the pen-holder.

Referring to these figures, A is the outer barrel of the pen-holder, andB isthe inner barrel. and held in' the usual way. Formed in one piecewith the inner barrel B is an extension or tongue, D, whose'outerGildgGXtBIldS forward, so as to be in close proximity to the under sideof the pen 0, and this end is bent into tubular, or approximatelytubular, form, to constitute a clasp which shall receive and hold'theink-solid d. This ink-solid is in the shape of a stick, like apencil-lead or a crayon, and can readily be inserted in, or. withdrawnfrom, the clasp. When in place it is in contact,'or almost in contact,with the under side of the pen, and is so positioned that when the penis dipped in 1iquid-as, for instance, water-the liquid taken up willdissolve a portion of thewriting material, thus producing awriting-fluid which will produce marks like those of ink.

The ink-solid I in preference use possesses copying properties, beingcomposed of aniline combined with white clayand gum, or other suitablebase or binding medium'such a core or stick, for instance, as is foundin the ink I copying-pencil, so called, now in market.

In each Fig. l and 2 the clasp is made in one piece with the innerbarrel of the holder, the two clasps differing only in form. Fig. 4 is aperspective view of the inner barrel in Fig. 1, detached from the otherparts of the pen.

I prefer that the tongue D should be a spring, or'have a slight springaction, so as to have a slight hearing at its point against the pen.

It is also preferred that the jaw of the-clasp or tube should besomewhat elastic, so as to take better hold on the ink-stick. In Fig. 3the device for holding the ink-solid is made of wire, E, bent at itsfront end toform a hook or ring, or segment of a ring, sufficient toreceive and hold the ink-stick cl, which, by the spring action of thewire, is held up against the under side of the pen, as shown. The innerend of the wire is made fast to the pen-holder, and when, as in thepresent case, the holder is arranged to slide in a case, F, the wire canextend out into and through the sliding ring Between the two the penG isinserted G, thus forming the bond of union between the holder andthe-external ring, bywhich the holder is moved. 4

The outer end of the wire spring may, if preferred, be formed only witha slight bend or concave suflicient to fit the ink-stick, which, in thiscaseywill be held in place by the pressure of the spring between saidspring and the pen. Fig. 5 is a detached view of the inner barrel andthe spring-clasp. (Shown in Fig. 3.) I would remark that the clasp maybe at I tached not only to the holder, but also to the handle, or to thepen itself. I prefer, however, on most accounts,rto attach the clasp tothe holder.

What I claim, and desire to secure by Letters Patent, is-- '-1. Thecombination, substantially as set forth, of the pen, the clasp, and thedetachathe pen-holder, the pen proper, and the inksolid spring-clasp,arranged to bear against or toward the under side of the pen with ayielding pressure, asand for the purposes specified.

In testimony that I claim the foregoing as my own I hereunto afiix mysignature in presence of two witnesses.

HENRY O. BENSON.
